Eatented Feb. 27', 1906.

Application filed August 25, 1905. Serial No. 275,830,

" a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented a new and useful Horseshoe-Calk and Fastener, of which the following is a specification.

This invention relates to improvements in horse shoe-calks and the means for fastening thesame, and has for its object to ro vide a simply-constructed and easily-app ied de vice of this character which may be attached to any of the Various sizes and forms of horseshoes in use and b means of which the calks maybe securely locked in position on the shoes, while at'the same time readily detachable, when re uired, without removing the shoes from the ioofs of the horses.

With these and other objects in view, which will appear as the nature of the invention is better understood, the same consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted b like designating characters, is illustrate the referred form of embodiment of the invention capable of carrying the same into practical operation.

In the drawings, Figure 1 is a perspective view irom beneath of a horseshoe with the improved calks and then fastenlng means applied. Fig.2 is a sectional detail illustrating the manner of constructing and applyin the improved device. Fig. 3 is a sectiona detail of the parts shown in Fig. 2 viewed from another oint Fig. 4 is a perspective. View of the bolting-plate, and Fig. 5 is a per spective yiew'of one of the improved call-rs detached. Fig. 6 is e view similar to Fig. 3, illustrating a modification in the construction.

The improved. device may be a plied to any size or'iorm of horseshoe an may be em loyed in connection with both the heel and toe callrs, and for the purpose of illustration is shown applied to all the calks on the shoe, (represented at 10.)

The improved callrs 11 are in l. shape with one arm 12 sharpened and the other arm provided with a olt-aperture lil, and the shoe 19 is provided at the points where the calks are to he attached with threaded apertures i i receive the cap-screws 15. whereby the CFllliS are secured in position upon the shoe. The toe-call member will preferably be in one single piece with two bolt-apcrtures to receive two of the cap-screws, as in Fig. 1, while the heel-calhs are of smaller length or corresponding to the width of the heel portions of the shoe.

A. locking device is provided for each of the cap-screws, consisting of a plate 16, provided with a bolt-aperture and with the material of the plate next to the arm 12 of the call:

greater in length than the distance between the aperture 13 in the calk and the adjacent:

face of the arm 12 of the calk, as shown at 20, so that when thelocking-plate is placed in position upon the calk the aperture 17 in the plate will overhang the aperture 13 in the calk. By this arrangement when the capscrew is turned home into the threaded aperture in the shoe the head of the bolt-bears upon the plate and compresses it a ainst the base portion 11 of the calk an likewise bonds the edge 19 against theprojecting portion 12 of the calk, as shown more clearly in Fig. 2, thus causing the plate to be firmly compressed against the bolt transversely,

while at the same time exerting a strong force outwardly against the head of the bolt by the reaction of the plate and eflectually prevent- As an ing retrograde movement of the bolt.

additional holding means one or more cor-' here of the locl 1ngplates may be bent against the sides of the head bolt, as at 18.

Havin thus described the invention, what is claims is- 1. Ahorseshoe and a horseshoe-call: provided with alined bolt-apertures and a rojection extending from said calk, a lockingplate bearing against said calk and provided with an intermediate boit-aperture, the material at one side of the aperture in said plate being of greater distance than the distance between the a erture in said calk and the projection on t. a same, and a bolt engagin I sai apertures and hearing by its hea against said locking-plate and bending the -(excess material therein against the projection, the plate being thereby caused to exert a pressure transversely of the bolt and likewise outwardly against the head of the same. I

2. A horseshoe and a horgeshoe-calk provided with alined bolt-apertures and a projection extending from saideallr, a locking portion of the p plate hearing against said ealk and provided with an intermediate holtszlperliure, the material :11, one side of the aperture in said plate being of greater distance than the distance bet-Ween [.he aperture in said eulk and the projeeliion on the some, and n holl engaging said apertures and hearing by its head against said looking-plate and bending the excess material therein against the PI'OJOC- CHARLES FREDERICK HARDING.
